Solution

Glutathione peroxidase is an enzyme that plays a key role in the body's detoxification system and helps protect cells from oxidative damage. It breaks down:

  1. Lipid Peroxides: These are harmful by-products of fat metabolism. Glutathione peroxidase helps to neutralize these potentially damaging molecules.

  2. Hydrogen Peroxides: This is a type of reactive oxygen species (ROS), which can cause oxidative stress and damage to cells and tissues. Glutathione peroxidase helps to convert hydrogen peroxide into water, thereby reducing its toxicity.

  3. Oxygen Peroxides: This term is not typically used in the context of biochemistry or physiology. It may be a misunderstanding or misinterpretation of hydrogen peroxide or other peroxides. Therefore, it's not correct to say that glutathione peroxidase breaks down "oxygen peroxides."

So, the substances that glutathione peroxidase breaks down are Lipid Peroxides and Hydrogen Peroxides.
